ughh not rumors again...
basically, I think it can go two ways.
positive side of things:
they do the presentation inside their campus, so they can practically have every single xbox tech guy in there to show and celebrate.
console is great, so they want to show us in detail how they stepped up bigtime.
hardware is number one, but software is magic too.
fucking console is so good that nobody wants to see the cod demo, and would prefer just staring at the new os for the rest of the presentation. ecstatic gaming journos throw their wallets at don mattrick, and proceed to pick him and the entire xbox team up on their shoulders and take them out on a glory parade around redmont. microsoft wins.
not so positive side:
they do the presentation inside their campus, so that they have a better chance of escaping with their lives from the angry mob they'll create. secret basement door located on soccer field so they can escape from tent after speaking.
console is a complete dud, and even worse, brings all drm shit and spy camera bullshit that you could fear.
no matter their plan for escape, many of the xbox "design" team are caught and fall victims to angry mob gaming press. things escalate, ms misses e3, people of redmont kick ms hq out of redmond etc etc.
whatever of the two it is, anything I say or you say, it cannot change the reality that we will finally see come tuesday 8)
I predict that either outcome will give us a good laugh, so its win-win basically
but please do not get hyped on pastebin! if it is that you want to get hyped, get hyped because both previous times microsoft has delivered.
